Where to download the Connector for Outlook (Free Edition)

hi there zimbra gurus,

our company recently shifted to zimbra, and since i'm used into microsoft outlook interface, and as i browsed through the web, i found out that this is really possible to receive mails on outlook so i downloaded the connector (ZimbraOlkConnector-5.0.5_GA_2199_5.0.2580.5) but the problem is when i configure the username, server name and etc... then i clicked apply... there's an error message, prompting that the connector i am using is for the network server , instead i must use the Free Edition...
by the way, i'm using Microsoft Office 2003

anybody knows here where to download the free edition? your help is very much appreciated.
